M Sleeping Bag

For a NATUREHIKE tent, waterproof means that all external fabric has been coated with our exceptional polyurethane coatings and the seams are watertight out of the bag. "mm" refers to millimeters and is paired with a number to represent a standardized measurement of how waterproof a coating is. For instance, a 3000mm coating will withstand a 3000mm (9.85') column of water for more than one minute before a single drop might appear through the fabric. That's strong enough to prevent rain from leaking into a tent in a hurricane-force storm.

We no longer sell parts separately. All products purchased through the NATUREHIKE website if there are product parts damaged, you can email us with your order and a picture or video proof of your damaged parts, we will give you a satisfactory answer. According to the actual situation of the warehouse, we try to replace your parts for free. E-mail: support@naturehike.com

"D" stands for Denier. It's a numbering system for fibers, filaments and yarns, in which the lower numbers are lighter/finer and the higher numbers heavier/coarser. "T" stands for Thread Count – specifically the number of warp and fill threads in a square inch. The lower numbers represent a loosely woven fabric and the higher number a tightly woven fabric. These two numbers together help indicate the strength and feel of a piece of fabric.

Waterproof performance: waterproof performance itself depends on the tent surface silicon coating, and fabric material has nothing to do with. naturehike tent in the production of general requirements: 210T, 15D waterproof performance is roughly 2000-3000mm; 20D waterproof performance is roughly 3000-4000mm, slightly better and 210T material.
Weight: the same tent weight comparison of different material styles ——210T > 20D > 15D

We expect to start reverting to global logistics in Sep 2022 and we are actively working towards this. Currently only the US can ship normally and some shipments from Canada and Australia can be sent out normally.

Never pack or store your tent if it is wet, damp or dirty. Although we use the best polyurethane waterproofing available, prolonged exposure to moisture causes hydrolysis which, in turn, causes the waterproof layer to break down, becoming soft, sticky and no longer waterproof. Storing a wet tent for as little as 24 hours in warm weather is also likely to start the process of mildew forming on the fabric. Mildew will cause your tent to stain, smell and will also lead to the premature breakdown of the waterproof coating. Mildew and moisture damage are not covered under the Limited Warranty.

For long-term storage, keep your tent in a dry and cool area, out of direct sunlight. Store it outside of its stuff sack, as you would a sleeping bag, in a breathable, over-sized cotton or mesh duffel for protection. On the cheap, an old pillowcase is ideal.

Condensation is the build-up of moisture inside your tent due to differences between the inside and outside temperatures. There are three main sources:

Weather Conditions:High humidity, low temperatures, and rainy conditions create the most condensation.

People:We produce about 1 - 2 pints of moisture per night through breathing and skin evaporation.

Wet Environment:Wet ground or wet gear stored inside the tent.While no tent design can eliminate condensation, the key to reducing it is ventilation. Cooler, drier air has to flow into your tent and warm, moist air must escape. We have designed a variety of ways to do this.

To start, the tent body and ceiling are made of breathable and mesh fabrics. This allows moisture to escape the interior of your tent. However, it must also be able to escape the waterproof fly, and every MSR rainfly has a peak vent that provides protection from the outside, while still allowing essential, free-flowing fresh air to move through your tent. You can also leave a door open in good weather, or take advantage of the double sliders on the doors to vent from the top where warm and moist air tends to accumulate. Make sure to leave at least two vents open if possible, allowing any breeze to provide cross-flow ventilation for maximum circulation. Guying out your rainfly will also increase ventilation in hot or humid conditions.

One of the easiest ways to damage your tent is by not drying it as quickly as possible after it gets wet. Storing a wet tent for as little as 24 hours in warm weather is likely to start the process of mildew formation. Mildew can permanently damage the waterproof coatings by causing them to separate from the fabric, but mild to severe staining is more common. Mildew stains are permanent. They cannot be removed without potential harm to the fabric coatings and are not covered by warranty. Even when your tent appears to be dry after use, it is always best to assure it is completely dry before storing. Hang it outside or pile it loosely in your house for a few days, turning it inside and out to assure it has dried everywhere. Never machine dry your tent as the heat can melt the fabric.

Cleaning your tent is not necessary unless it has an offensive odor or becomes heavily soiled. If heavily soiled, the pressure from a regular garden hose will remove most loose dirt. For more severe cleaning, set up your tent and hand wash it with warm water, a sponge and mild, non-detergent soap. Do not use dishwashing liquid, detergent, bleach, pre-soaking solutions, or spot removers. Rinse well. Dry your tent by pitching it or line-drying it. Never dry clean, machine- wash or machine-dry your tent. Any of these methods can remove all the waterproof coatings from the tent.
